 Bovey Deposits. (Jouin. Torquav nat. Hist. Soc. I. 1. p. 21 — 23. 



1909.) 

 From a boring in the potteries the general succession of the 

 beds is seen to be a) Beds of clay and sand with occasional lignites; 

 b) Beds of lignite and clay with one of sand; c) Beds of lignite with 

 thin layers of clay. The thickness of these "Eocene" deposits is 

 estimated at a total of 613 ft. The most interesting beds are the 

 lower lignites which the present author considers to have been 

 deposited in situ. The evidence for this is principally the nature 

 of the plants themselves, several of the plants otherwise described 

 by Heer have been shown recently to have been swamp lovers. 

 The author suggests that the higher beds in the series may prove 

 not to be of Eocene age, but to be even as late as Oligocene.

Abstract of paper read at the Association meeting on a well pre- 



served Russian petrifaction of the genus Tempskya the plant appea- 



red to have formed "false stems" growing erect to a height of 9 ft. 



or more. These are formed of an aggregate of several narrow 



solenostelic stems felted together by rootlets. The authors suggest 



that modern tree ferns may have been derived from Tempskya-lxke 



ancestors. M. C. Stopes.

A redescription, with tigures, of Dawson's species of Dado xylo) i 

 wood from the sandstones at St. John, N. Brunswick. This is 

 followed by the re-description of several known plant impressions, 

 and the description of some new species from the same deposits. 

 The impressions of foliage described by Dawson as Alethopteris 

 discrepans and of fruetifications called by him iporangites acumina- 

 tus are together included by Matthews in a new genus Johamio- 

 phyton. The allocation of the fruetifications to the foliage being 

 based on association. A new genus, Ginkgophyton is represented 

 by G. Leavitt which is supposed to be a Pteridosperm thongh the 

 fruit has not been found actually attached. Three new species and 

 a variety of Sphenophyllum are described, and three varieties of a 

 new species of Whütleseya. M. C. Stopes.
